The Super HETO’S body is pressed from a single piece of steel giving it perfectly smooth radius corners. This design allows the maximum amount of air to flow downstream making the system much easier to balance and saves energy. The Super HETO comes with and without volume dampers. The adjustable dampers are assembled using a spring loaded retractable bearing and positive locking hardware.
